ah...indeed...touch & technique mean more than which instrument..Think about a banjo being frailed,,,then about some gentle, tasteful melody pickin'...Then imagine a guitar being whanged in some beginners version of "The Sloop John B", as opposed to a soft, finger picked love song where the fingers sort of caress the strings...Even a properly done mandolin vibrato can be quite sensual....

so, with that said, I am off to practice triple-tonguing my recorder...
